A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21015-08\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. The piston carries the shim stacks and meters the oil through its ports. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 21015-08 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. This position has no published dimension, so the part number is the only reliable identifier. Öhlins machines its pistons so the port edges stay sharp and the flow predictable. Port area sets how much oil can pass before the shims begin to lift.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 21015-08\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Pistons\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53652472496394,"sku":"21015-08","price":11.17,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21015-08_b08128b9-f450-4735-8a73-e9fbfc3377e1.png?v=1788879304","url":"https:\/\/inter-pace.com\/products\/ohlins-piston-solid-36-21015-08","provider":"Inter-Pace","version":"1.0","type":"link"}
